The Chinese medicinal ginseng is root of Panax ginseng of Araliaceae, and has effects of invigorating primordial qi, invigorating spleen, nourishing lung, promoting salivation, quenching thirst, tranquilizing mind, improving intelligence, etc. The ginseng contains a plurality of active ingredients, wherein ginsenoside is one of the most main ingredients of the ginseng for playing the role. The ginsenoside has high content of Rb1, rb2, rc, rd, re and Rg1, but has low biological activity and low absorptivity in human body. The rare ginsenoside with higher biological activity has low content and is not easy to extract, and an additional preparation method is generally required. The current methods for preparing rare ginsenoside are 3: the main components in the ginsenoside are converted into rare saponins by microbial fermentation; the microorganisms such as escherichia coli, yeast and the like are modified by utilizing metabolic engineering and synthetic biology to directly produce rare ginsenoside; the main saponins are converted into rare saponins by glycosidases. However, the three preparation methods have complex processes, require a large amount of manpower and material resources, and are not beneficial to industrial production. Therefore, it is needed to provide a preparation method of rare saponins with simple process.

As shown in Table 3, the ginsenoside extract prepared by the invention has the whitening effect, can effectively reduce melanin deposition in skin after being used, lightens skin color, and has the effect obviously superior to that of a comparative example group.
Experimental example 3
The experimental examples explore the anti-hair loss and hair growth effects of the ginsenoside extracts prepared in examples 1 to 3, and the steps are as follows: healthy SD rats were selected 70, and randomly and evenly divided into 7 groups, namely, examples 1 to 3 groups, comparative examples 1 to 3 groups and control groups, wherein after each group of rats is fed with basic feed for 7 days, the back hair of 3cm multiplied by 3cm on the back is removed, the corresponding ginsenoside extract is smeared on the exposed skin of the rats from the group 1 to 3 of the examples 1 to 3 of the depilation and the group 1 to 3 of the comparative examples, and physiological saline is smeared on the blank control group. The amount of the drug applied to each group of rats was 1 mL/time, 1 time/d, and 12d of drug was continuously applied. The growth of the back hair of the rat was recorded before each application from 5d, and the hair growth of the rat was classified into 5 grades, namely 0, 1, 2, 3 and 4, respectively, "0" means no hair growth, "1" means little hair growth, "2" means obvious hair growth, "3" means good hair growth, and "4" means normal hair growth. The results are shown in Table 4.
TABLE 4 comparison of rat dorsum hair growth conditions
As shown in Table 4, the ginsenoside extract prepared by the invention can grow villi on the 6 th to 7 th days after being smeared on the exposed skin of rats, is obviously earlier than that of the comparative example group and the control group, and can reach the normal level on the 11 th to 12 th days. In addition, the skin of the rats in the examples 1-3 does not have allergy phenomenon in the experimental process, and the activity and ingestion of the rats are not influenced, so that the ginsenoside extract prepared by the invention has no irritation and has the effects of preventing alopecia and promoting hair growth.
